When I wipe there's a light spotting of pink blood. I don't know what is wrong. And I have cramps but my period isn't due until next week. What is going on wit me?

First of all how old are you-old enough to go to the gynecologist? If so go. You are experiencing break through bleeding. Are you on any birth control? Anytime something different for your body happens it's time to see the gynecologist. When making the appointment tell them what is going on so you can get an earlier appointment than if it was juft for a regular annual appointment.
